In continuation of our AO15-approved proposal, we hereby propose to completeXMM- Newton observations for a systematic study to calibrate cluster observablescaling relations, using precision, HSC-derived, weak lensing mass measurementsand make a stringent test of the assumption of hydrostatic equilibrium ofclusters. The exquisite quality of multi-band HSC imaging will enable us toimprove both the precision and accuracy of weak-lensing mass measurements. Bycombining these weak lensing mass measurements with deep X-ray and ACTPolSunyaev-Zel dovich effect data, we will have an unprecedented ability toconstrain the physical state of the ICM. Our project provides an essentialbridge to future, cluster-based, cosmological studies by eROSITA.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
